[Methods]24 new born piglets(Duroc×Landrace×Yorkshine)were chosen and assigned to three treatment groups. 8 normal birth weight piglets were allocated to normal birth weight(NBW)group,and 16 IUGR piglets were randomly assigned into IUGR group and IT(IUGR+tributyrin)group. All piglets were weaned at 7 day of age,and were fed with the artificial milk diets from day 7 to 21. Piglets in the NBW group and the IUGR group were fed with basic milk diets,while piglets in the IT group were fed with basic milk diets supplemented with 0.10% tributyrin. 6 piglets in each group were selected and sacrificed on day 21. [Results]The results showed that:1)The liver weight of the piglets in the IUGR group was smaller than that of the NBW group(P <0.05);the liver weight of the piglets in the IT group was higher than that of IUGR group(P <0.05)and the liver index of IT group was significantly higher than that of IUGR group and NBW group(P <0.05). 2)The content of insulin growth factor-1(IGF-1)in the liver of the piglets in the IUGR group was significantly lower than that in NBW group and IT group(P <0.05),but the content of IGF-1 in IT group was higher than that in NBW group(P >0.05). The contents of tumor necrosis factor-α(TNF-α),interleukin-4(IL-4)in the liver of the piglets in the IUGR group were significantly higher than those of NBW group and IT group(P <0.05),but there were no significant differences between IT and NBW groups(P >0.05). 3)The expression of IGF-1 mRNA in the liver of the piglets in the IUGR group was significantly lower than that in the NBW group and IT group(P %K 三丁酸甘油酯 %K IUGR哺乳仔猪 %K 肝脏 %K 发育 %K 免疫功能< %K /br> %K tributyrin %K IUGR suckling piglets %K liver %K development %K immune function %U http://nauxb.njau.edu.cn/oa/darticle.aspx?type=view&id=201505020
